Age Optimal Sampling for Unreliable Channels under Unknown Channel Statistics
Hongyi He, Haoyue Tang, Jiayu Pan +3
In this paper, we study a system in which a sensor forwards status updates to a receiver through an error-prone channel, while the receiver sends the transmission results back to t…

Age of Synchronization Minimization in Wireless Networks with Random Updates and Time-Varying Timeliness Requirement
Yuqiao He, Yuchao Chen, Jintao Wang +1
This study considers a wireless network where multiple nodes transmit status updates to a base station (BS) via a shared, error-free channel with limited bandwidth. The status upda…

Input-Output Relation and Low-Complexity Receiver Design for CP-OTFS Systems with Doppler Squint
Xuehan Wang, Xu Shi, Jintao Wang +1
In orthogonal time frequency space (OTFS) systems, the impact of frequency-dependent Doppler which is referred to as the Doppler squint effect (DSE) is accumulated through longer d…
